Christopher Konopka has announced wiiAirDrum, a MaxMSP application for triggering samples with a wiiMote controller.
I just finished working on a project I created months ago as a research project that involved creating musical applications for blind individuals. This was part of a Music Therapy Development group led by Dr. Richard Boulanger and Professor Chi Kim. The goal of my application for this project was to create a drum-like sampler that an individual could use instead of using an actual drum set. In essence, each remote can control 4 samplers which can be programmed manually or by using the controller. Each sampler is controlled by a button combination and can be triggered by making a drum-strike motion. These combinations are simple variations and each remote has the same combination setup.
wiiAirDrum is available as a free download.
